Esprima is no longer maintained, and it does not support the latest JavaScript features in ES11, as Espree does.
- **New Linter Integration:** Introduces `src/js/_enqueues/vendor/codemirror/javascript-lint.js` using `espree` for parsing and error reporting, replacing the dependency on `jshint` and `esprima` scripts.
- **Script Modules:** Registers `espree` as a script module and leverages the `module_dependencies` argument in `wp_register_script()` to ensure `espree` is available as a dynamic import.
- **Editor Settings:** Updates `wp_get_code_editor_settings()` to use ES11 (ECMAScript 2020) defaults and synchronizes JSHint settings from `.jshintrc` for compatibility.
- **Editable Extensions:** Adds `.mjs` to the list of editable file extensions for plugins and themes.
- **Deprecations:** Marks `esprima` and `jshint` script handles as deprecated.
- **Build Tools:** Updates Webpack configuration to bundle `espree` as a module and use the new local `javascript-lint.js`.
